Sometimes when people label something for sale with an "X" in it, that indicates the pairing that produced the baby, NOT the babies genetics.
So you may in fact have a normal bearded dragon, whose parents were a Pastel Tiger (male, for example) bred to a Citrus (female).
Mind you, I know ZERO about beardie genetics, and I'm not sure if that pairing could even produce any normals, but to me, the dragon in your pics looks like any other normal beardie that I have seen.
